A frequency spectrum shows a tone that is composed of a frequency of 440 h z, 880 h z, and 1320 h z. the 880 h z and 1320 h z frequencies are called. sine wave.

Frequency, in physics, the wide variety of waves that skip a hard and fast point in unit time; also, the variety of cycles or vibrations gone through for the duration of one unit of time via a body in periodic movement.

The variety of durations or often happening occasions of any given type in unit of time, typically in one 2nd. the variety of cycles or finished alternations in keeping with unit time of a wave or oscillation. symbol: F; Abbreviation: freq.

Frequency is an crucial parameter used in technological know-how and engineering to specify the temporal charge of change located in oscillatory and periodic phenomena, along with mechanical vibrations, audio indicators, radio waves, and mild.

Pertaining to simple machines and levers what changes when the fulcrum position is modified?
Inessa [10]

Explanation :

There are many types of simple machines i.e. lever, wedge, pulley, wheel and axle etc.

Fulcrum is the pivot point about which the lever turns. When the position of the fulcrum is shifted, the position of effort changes.

There are three classes of the lever as class 1, class 2 and class 3.

Class 1 includes seesaws and scissors.

class 2 includes wheelbarrow

class 3 includes tongs and tweezers.

Which of the following is a graph of the velocity of an object as it falls fromrest if drag is not ignored? Explain your choice
MariettaO [177]

The air drag is a force that depends on the speed of an object relative to the wind. Under certain conditions, it can be modeled as:

F=-bv

Where b is a constant.

As a falling object reaches a speed so that its weight is cancelled out by the air drag, the object will reach a maximum velocity.

In a speed vs time gaph, the speed would approach the maximum speed like an asymptote.

On the other hand, since the object falls from rest, the initial speed on the graph must be zero.

Taking these considerations into account, the correct graph for the movement of an object that falls from rest if air drag is not ignored, is option B.

How would the atmosphere of earth differ if the earth was much larger
Juli2301 [7.4K]
If the earth just doubles its size in an instant, the oxygen present in the atmosphere could be much larger. Due to these, we could theorize that insects could grow much larger because the size of their body is heavily dependent on the maximum amount of oxygen present in the atmosphere. Air pressure also increases thus those aerial enthusiasts would enjoy their professions.

How much work is needed to move an object from one position to another when both positions are located the same distance from th
Vladimir79 [104]

Answer:

<em>The product of the object's weight and the horizontal distance between the two positions.</em>

<em></em>

Explanation:

Work is the product of force and the distance through which this force is moved. The distance moved can be vertical, or horizontal. For two bodies located the same distance from the center of the earth, the work done will be the product of the weight of the product and the horizontal distance between the two positions. <em>If the vertical work is needed, then the work is zero, since there is no height gradient between them</em>.
